Heat Transfer Mechanisms

The present work distinguishes the thermal attributes of zirconium oxide (ZrO2) and single wall-carbon nanotubes (SWCNTs) in a three dimensional rotating frame under the magnetic field environment. Sodium alginate (NaC6H7O6) is assumed to be the base fluid. The slippage and convective conditions on boundary have also been incorporated. The analysis comprehends, comparatively, features of both SWCNTs-NaC6H7O6 and ZrO2–NaC6H7O6 nanofluids. The amalgamation of nanomaterial SWCNTs-ZrO2 in sodium alginate builds up the thermal characteristics. An algorithmic approach deals with the approximate solutions of the problem. The numerical algorithm is mainly based on order reduction and central difference discretization. A comparison, in limiting case, appraises the proficiency of the code. The outcomes are physically and numerically interpreted via graphical and tabular representations against the prime parameters. The nano-composition of SWCNTs-ZrO2 convincingly improves and embellishes the heat transport rate. It has been revealed from the results that higher the microrotation parameter Ω0, higher will be the thermal boundary layer thickness in both cases of nanofluids such as SWCNTs/NaC6H7O6 and ZrO2/NaC6H7O6. A sensible judgment of the outcomes discloses that SWCNTs possess, comparatively, better heat transfer features than zirconium oxide.
